  • Publication number: 20190165480
    Abstract: Examples disclosed herein relate to methods and apparatuses for a radiating structure to radiate a transmission signal, where the radiating structure incorporates reactance control elements to change a reactance of transmission lines and/or radiating unit cell elements, and a resonant coupler to isolate the transmission signal from a reactance control signal to the reactance control elements. A reactance control signal, such as a bias voltage, controls the reactance of transmission lines of the transmission array structure and/or the radiating unit cell elements so as to change the phase of the transmission signal, thereby steering a beam of the transmission signal. The reactance control elements may be incorporated into a microstrip within the transmission lines.

  • Publication number: 20190028304
    Abstract: In examples, Time-Reversal (TR) Orthogonal Frequency-Division Multiplexing (OFDM) communications employ adaptive filtering on a per-subcarrier basis. Matched filtering is used for subcarriers with poor transmission properties (such as relatively high channel attenuation), while inverse filtering is used for subcarriers with relatively good transmission properties (such as relatively low channel attenuation). Modulation order may be reduced for the subcarriers with poor properties (relative to the subcarriers with good properties). The discovery of subcarrier properties may be performed through the channel state information measured and reconciled from single- and/or bi-directional TR sounding signals. The discovery may be repeated, for example, performed continually. In response to changes in traffic and other environmental conditions, the system may be reconfigured dynamically with different subcarriers selected for matched and inverse filtering.

  • Publication number: 20180091205
    Abstract: In examples, two arrays of Radio Frequency nodes achieve enhanced beamforming for communications between the arrays by successively sending sounding signals from one array to the other array. Each sounding signal sent by the first of the two arrays is beamformed through time reversal of an immediately preceding sounding signal received by the first array from the second array, and each sounding signal (except the initial sounding signal) sent by the second array is beamformed through time reversal of an immediately preceding sounding signal received by the second array from the first array. The initial sounding signal sent by the second array may be omnidirectional, beamformed through a guesstimate, random, predetermined, or determined through a search of the area where the arrays are located. With sufficient beamfocusing, the arrays may communicate by sending and receiving data from one array to the other array.
